[Utah-astronomy] M-82

I was between data taking projects tonight so I refocused the scope for the warmer temps that may finally be arriving. Once finished I shot five 30" test images of M-82 and stacked them. http://users.wirelessbeehive.com/~paw/temp/M82.JPG I'm satisfied with the focus and I like the spiral arms and the detail near the core but wish I knew how to keep the core itself from burning out. patrick
